There are many transformers and coils in use inside the TV. These are coils of wire wrapped around a central core. Sometimes, especially in the yoke or horizontal linearity coil, the core will "sing", making a noise from the back of the set. This is normal, but if it is too annoying then the part making the noise will have to be replaced, and that should be done by a qualified tech.

Is this sound comming from the speakers or from the inner works of the set? If from the speakers then you may have a bad cap in the audio section, I usualy look for a 1000uf, they have been known for that. If the sound is from the inside of the set then follow what Mike said earler.

Hello
Just make the picture status button on the remote control and get the display setting to its factory mode.

The VIDEO STATUS button gives you a choice of three TV picture display settings, including a
display of your own preferences.
Standard - Resets the picture display to the factory settings.
Dynamic - Heightens contrast.
Theater - Gives a rich, film-like look to video. (AV-27D303, AV-27D203 and AV-20D303 only)
Sports - When you watch a sports program. (AV-27330, AV-27320 and AV-27S33 only)
Press the VIDEO STATUS button repetedly to get these choices.

The sound on my tv is off and i dont know how to turn it on?

some tv's have a button on the back that will turn on or off the built in speaker system so that the tv can be plugged into an external system and allow the user to use the tv's volume control for the ext. speakers without hearing the internal ones, if there is no such button check the tv's setup menu for a setting that enables or disables the speakers

There is most likely the main power supply has several shorted parts in it, depending on how old it is, it might be worth at least an estimate. if you have homeowners insurance, you may want to concider reporting this to them. Good Luck
